A case of omental endometriosis complicated by hemorrhagic ascites leading to pelvic encapsulated effusion

This case report investigates the rare occurrence of omental endometriosis presenting with significant hemorrhagic ascites and pelvic encapsulated effusion in a premenopausal woman, despite the absence of typical endometriosis symptoms or prior pelvic surgery. The authors emphasize the need for clinicians to consider omental endometriosis as a potential diagnosis in similar cases, particularly when serum CA125 levels are elevated but HE4 levels remain normal. The findings highlight the importance of thorough preoperative evaluation and tailored surgical approaches in managing such complex presentations.
